I thought you were joking about signing another 8.....but alas not.
I wonder if you'll look to convert someone to 7 full time or maybe Garvey back to a lock and someone else at 6.
Well, last week we started a lock at OSF, and our last centre went off injured. Whilst our need may not be for wingers and #8s specifically, I think we're just signing up bodies wherever we can get them on short-term contracts for the time being.
Houston is only here until Super rugby pre-season starts in November.
Brew's contract is only until the new year.
Knight, Grant and Wilson (if confirmed) will only be until the end of the season (at most).
Remember, we had the smalles squad in the Prem to start with (which Ford wanted, and then we couldn't recruit without a head coach) which has been ravaged by injury.
IIRC we started the season with 35 seniors, then promoted 2 up from the academy. I think our injury list is 1LHP, 1-2HK, 2THP (1 departed), 2LK, 4BR (+1 absent), 2SH, 1FH, 3CE.
We're down to 2 LHP, 2-3HK, 1THP, 2-3, 2LK, 1BR, 2SH, 1FH, 0CE, 5WG from our original 37.
Out mid-season "transfers" have swapped a fit THP for an injured one, recruited 1#8 who's already here, and another for when he goes again 1 wing who's already here and another for when he (is due to) leave and an OC who won't be here for another 4 weeks.
